About Us

About Johnny

I began collecting stamps around about 1950, coins about 1956.  Trained in an Auckland Department store in 1960, I was taught to give good service to our customers.

Later I was the director of Britannia Coins in Dunedin, 1981 to 1988 ~ and the director of Otago Coin, 2002 until now.  Nothing but the very best is good enough for my clients.

Your satisfaction must come first.  Look at my feedback.  I want you to be happy with your purchase and to return to Otago Coin.  If you sell to us, I hope you will recommend us to others, as many have already done.

I am open with information, about values and about the marketplace.  I am now elderly and in surprisingly good health.  Please call me Johnny.

My credential is: Johnny Lindsay B.A. (Otago University).

Sandra ~ is the one I consult every day about the running of the website and the business. Sandra does not get the attention that I get but her input is as important as mine is.

Those polymer plastic albums you can put your coins in. They are smart when new. You can see your coins front and rear and some even have a paper backing-page to write on your details. But hang on a minute. What will these coin pages look like in twenty years?

If you live inland away from the coast and the salt-laden air, there may not be too much of a problem. Say about five miles is fairly safe. How about if you live at Takapuna, Mission Bay or Brighton? Then expect after about ten years, to see those coins begin to show green rings around where they rest in the pages ~ and on the pockets themselves.

After twenty years it gets worse. Then the nice plastic becomes a little cloudy. Forty years on, the cellotape placed to keep the coins from falling out ~ that has yellowed, or worse, it becomes a sticky mess once you try to remove it.

Is there an answer? I’m an oracle not a scientist but here are a couple of tips. Do not buy these plastic albums for your coins. You can keep your coins in see-through flips, made of mylar, not plastic. Mylar is inert. It does not react with the copper component in silver and bronze coins. Acetate is okay but there are no guarantees with it.

Keep your flips in a storage box, such as you keep photo slides in. Dansco coin albums are good. But they are expensive and are made in the States. How do I know all this? When I buy large coin collections that had been stored in plastic albums for forty years or more ~ sometimes I have to use scissors to cut through all the sticky pages to get the coins out. Then I have a problem conserving coins that are oxidizing. Some coins are so bad they just go into scrap metal containers or the waste bin.

Granddad failed to see his coins deteriorate. He loved placing those coins in his brand new albums. Put away and forgotten, chemical reactions never sleep.
